OK you sous vide nerds, educate us

[FireFlyFishing]

I really want to try this, I have a immersion circulator, but it seems like a poor design, designed to clamp to the side of a pot. I would think that evaporation would be an issue on long cooks.

Insta Pot w/sous vide a viable option?

So, recommend:

Cook books?
Sous vide machine or kit?
Standard vacuum bags, yea or nay?
Weights, yea or nay?
How to control evaporation?

Anything else we should know? Anything we must have before we start?

Thanks!

Check out Sous vide everything on YouTube. Great channel. Very Entertaining and family friendly. Guga helped me get into the sous vide world. In fact, my wife now eats venison when she was a hard no before. Start with the early vids.
